To evaluate and synthesize the evidence from the individual reviews that evaluated the efficacy of PDT therapy in root canal disinfection by undertaking an umbrella review. The protocol of the review was registered in the PROSPERO database under number CRD42021214056. The literature search was conducted using the following electronic databases: PubMed, Scopus, Web of Science, BVS, Cochrane Database of Systematic Reviews, Embase, and Epistemonikos, from inception to July 2021. Systematic reviews that evaluated the efficacy of PDT for root canal disinfection were included. Two authors independently performed a literature search, data extraction, and quality assessment of the included studies. Any disagreements were resolved by a third reviewer. The quality of the reviews was assessed using the AMSTAR 2 tool and the final categorization of each systematic reviews was classified as of "high," "moderate," "low," or "critically low" quality. Six systematic reviews were included in the current umbrella review and all of them were graded as critically low quality. From the critically low-quality evidence available, this umbrella review showed that the efficacy of PDT in root canal disinfection remains yet undetermined.
为了通过伞式审查评估和综合评估 PDT 疗法在根管消毒中的疗效的个别综述中的证据。该综述的方案已在 PROSPERO 数据库中以编号 CRD42021214056 进行了注册。文献检索使用了以下电子数据库：PubMed、Scopus、Web of Science、BVS、Cochrane 系统评价数据库、Embase 和 Epistemonikos，从开始到 2021 年 7 月。纳入了评估 PDT 治疗根管消毒效果的系统评价。两位作者独立进行了文献检索、纳入研究的数据提取和质量评估。任何分歧均由第三位审稿人解决。使用 AMSTAR 2 工具评估综述的质量，对每个系统综述的最终分类为“高质量”、“中质量”、“低质量”或“极低质量”。目前的伞式综述纳入了 6 篇系统评价，均被评为极低质量。从现有的极低质量证据来看，本伞式综述表明 PDT 在根管消毒中的疗效仍不确定。
